Abstract :
Arrays with good correlation properties are required for code-departure imaging, as well as for other applications of two-dimensional signal processing. Since binary arrays with perfect periodic autocorrelation are rather sparse. `pseudoperiodic´ binary arrays are discussed. The transmitted binary array is correlated in the receiver with the same array which is surrounded periodically by similar ternary arrays. A construction method is presented that permits the construction of such `pseudoperiodic´ binary arrays with perfect correlation properties for all sizes p1a1×p 2a2 (p1, p2 odd prime, a1, a2=1, 2, 3...)
